Main object of thsi study is to know tendency or rend of studies on tea manufacturing machinery, chiefly after the war, by treating it from three directions, such as the estimation from commercial conditions, analyse of literature published from above 12 tea researching organs all over country, and studies dealt by machine makers.
The summary of these are as follows:-.
I Guess from commercial conditions.
(1) Influenced by interior demand and export.
(2) Discontinued by the war.
(3) Progressed and recovered satisfactorily after the war.
(4) Studies on green tea lengthen, “tencha” and “gyokuro” for interior demand.
(5) Moreover studies on tea parching raised powerfully for export.
(6) By the decrease of export of green tea and the increase of black tea for America, studies on black tea became influential.
II Analyse of literature.
(1) Weight of studies on tea manufacturing machinery. Both number of titles on tea manufacturing machinery divided by total titles of a literature, say x, and number of pages used for studies on machinery divided by total pages, say y, were about 25%.
(2) Progress of titles Since 1947 (Showa 22) studies of direct heating furnace treated for want of fuels, have progressed steadly in 1950 (Showy 25) kept pace and regulated gently, on fundamental studies, such as mechanism of drying, tea leaf tissues and forms, and studies on tea lengthen, tea parching and black tea.
(3) Recent titles
1. Tea leaf parching machine for export.
2. Oil fuel burning apparatus.
3. Tea leaf pressing machinery and its process
4. Continuous tea manufacturing machinery, etc. are treated according to the speciality of researching institution.
III. Studies dealt by tea machine makers.
(1) In the common green tea lengthen machine the reseacher laid stress on steaming machine, finish rolling machine, and endeavoured to supply good machines in low price.
(2) Tea leaf parching machines.
(3) Liquid fuel (crude oil) burner.
(4) Big black tea leaf rolling machines, etc. are being studies in details.
